Device for identifying stamping characters of doorplate based on caffe and soft trigger

Abstract

The invention provides a device for identifying stamped characters of a doorplate based on caffe and soft trigger. The device comprises a hardware collection equipment module and a software processingprogram module, wherein the hardware collection equipment module is used for obtaining an image of the stamped character; a camera collection module is used for obtaining and collecting the image, the type is distinguished, and the product information is improved; a shooting module is triggered by software to collect the image; the software processing program module is used for processing the obtained image, splitting the characters and identifying. The device adopts a method with the following steps of firstly, detecting whether the image contains a circle shape with specified size or not, acquiring the satisfactory image, and avoiding overlow definition degree of the collected image; providing a floodfill algorithm to determine the positions of the characters, and eliminate the interference background; finally, calling caffe and LeNet-5 handwriting font identifying networks to learn and identify. Compared with the traditional feature extracting algorithm, the accuracy is obviously improved.

Description

technical field [0001] The invention relates to the technical fields of image processing and character recognition, and in particular to a house plate embossing character recognition device based on caffe and soft trigger. Background technique [0002] In the industry, there is a great demand for the recognition devices of house plate embossed characters in many production lines. The existing industrial-oriented embossed house number character recognition devices mainly have the following limitations in terms of image acquisition, character processing and recognition Insufficient, room for improvement: [0003] First of all, the common embossed house number character recognition device mainly focuses on image acquisition and triggering of photographing by using hardware to trigger image acquisition modules for image acquisition. Due to hardware installation conditions, there are too many limiting factors, such as: venue, environment, light and other conditions, so it is oft...

Problems solved by technology

Based on the traditional template matching and feature extraction recognition technology, the character recognition effect is better in an ideal environment; however, with the complexity and diversification of the production environment, on the one hand, it is often difficult to find the most suitable features by artificially selecting character features; The character recognition effect of the traditional method is not good in complex scenes, and it is difficult to recognize the characters of the house number in real time and accurately
